Question 1

How does conversational AI work?

Accepted Answer

Conversational AI works by turning a person's speech or text into structured meaning with natural language understanding, keeping track of the conversation's context, deciding the next step with a dialogue manager or language model, retrieving information or calling systems to act, and generating a natural reply in text or synthesized speech.

Question 2

Is conversational AI the same as a chatbot?

Accepted Answer

A chatbot is one application. Conversational AI is the broader technology that lets machines understand and respond to human language, in text or voice.

Question 3

What is natural language understanding?

Accepted Answer

NLU is the part of conversational AI that works out what a user means: their intent and the details, such as dates or order numbers.

Question 4

Does conversational AI use machine learning?

Yes. Modern systems rely on machine learning models, especially large language models, for understanding and generating language.
